DESCRIPTION¶
vtprtoff is a simple program that turns off (or on) redirection of ASCII
text to a printer connected to a terminal or terminal emulator. It uses
terminal escape sequences to achieve this end.
OPTIONS¶
- -d
- Use the tty device file instead of stdout for output. This is defined as
/dev/tty on this system. (This is operating system specific and may
vary from system to system.)
- -D
- Use the stdout stream for output, rather than a tty device file.
- -e
- Forces vtprtoff to ignore the TERM environment variable and use the
builtin control codes instead.
- -E
- Undoes the effect of the -e option, which allows vtprtoff to
attempt to find an entry in /etc/vtprintcap for the TERM value and
use the corresponding control codes.
- -h
- Print out a simple usage message.
- -l
- Print out the license agreement.
- -L vtprintcap
- Specifies an alternate file to use instead of /etc/vtprintcap.
- -q
- Quiet mode. Suppress various status messages from being displayed.
- -Q
- Cancels the effect of the -q option, allowing normal progress
reporting to occur.
- -t
- Force the use of the TERM variable to perform a look up of the control
sequences to be used in /etc/vtprintcap. If an entry in that file
can't be found, vtprtoff will abort with an error.
- -T termtype
- Use the value of termtype instead of the value of the TERM
environment variable when performing lookups in
/etc/vtprintcap.
- -v
- Display version information.
- -V device
- Specifies an alternate device file instead of /dev/tty to use.
- -w
- Display important warranty waiver information. NO WARRANTY!
ENVIRONMENT¶
- TERM
- the type of the terminal vtprtoff will assume is being used.
- VTPRINT
- string of options to be used by vtprtoff.
